Abstract: A sensor, system, and method for detecting and correcting for an effect on an analyte indicator of an analyte sensor. The analyte indicator may have a first detectable property that varies in accordance with an analyte concentration and an effect on (e.g., degradation of) the analyte indicator. The analyte sensor may also include an interferent indicator having a second detectable property (e.g., absorption) that varies in accordance the effect on the analyte indicator. The analyte sensor may generate (i) an analyte measurement based on the first detectable property of the analyte indicator and (ii) an interferent measurement based on the second detectable property of the interferent indicator. The analyte sensor may be part of a system that also includes a transceiver. The transceiver may use the analyte and interferent measurements to calculate an analyte level.

The sensing devices may be configured to only perform activities (e.g., conveying measurement data) in response to addressed commands (e.g., addressed read measurement data commands) if the sensing devices determine that the addressed commands are addressed to them.
